Why not an 7-substituted-DHEA product, like LeanFX? I try to stay away from calling them anti-coristol supplements because (1) they do a lot for thyroid metabolism through different route than supplements labelled as "thyroid products" (2) you really need *some* cortisol in your body to burn fat, these products merely keep it under control.

In the case of taking a stimulant, the biggest "room for improvement" area in terms of burning fat comes from the fact that stimulants increase cortisol levels. By combining a product to control corisol levels, you'll find it works in synergy with stimulants to burn fat.
